TETHEvRlNG-PIN.

SPECIFICATION forming part of Letters Patent No. 716,010, dated December16, 1902.

Application filed June 2, 1902.

To all whmn it may concern:

Be it known that I, REUBEN C. ELDRIDGE, a subject of the King of GreatBritain, residing at Niagara Falls, in the Province of Ontario, Canada,have invented new and useful Improvements in Tethering-Pins, of whichthe following is a specification.

This invention relates to a pin or stake more particularly designed fora tether-ingpin, the body of which is formed of a sheetmetal blank bentinto shape.

One object of the invention is to provide a strong durable pin which isof simple and inexpensive construction and which will not be injured indriving the saine into the ground with an ax or other tool or device.

Another object is to provide a swivel connection for the tether whichwill enable the free movement of an animal in grazing and prevent I(hetether from being vtwisted or wound on the pin.

In the accompanying drawings, Figure l is an elevation of atethering-pin embodying the invention. Fig. 2 is a longitudinal sectionthrough the upper portion of the pin. Fig. 3 is a plan view of a blankfrom which the body of the pin is formed. Fig. 4 is a plan view of thebody partially formed.

Like letters of reference referto like parts in the several figures.

A represents the body of the pin, which is of substantially trough or Vshape in crosssection to afford the requisite transverse strength to thepin and provide longitudinal Web portions or sides d, which give the pinan extended bearing and rm hold when in the ground. The body preferablytapers gradually from its upper portion to its lower end to enable it tomore readily penetrate the soil.

B represents a head or post which is 'of` substantially cylindricalshape and is embraced by and rmly secured in a cylindrical socket C atthe upper end of the pin-body. The connection of the head or post withthe body is made more secure and permanent by one or more interlockingannular beads and grooves on the post and socket. Preferably the post isprovided with a bead d, which engages in a cooperating groove in thesocket, and a groove e, in which engages an inwardlyprojecting bead onthe socket. In order to Serial. No. 1 09.86 5 (No model.)

prevent the head post from being driven down and loosened in its socket,it is provided with an outwardly-projecting annular shoulder F, whichover-hangs the top of the socket. In driving the pin into the groundthis shoulder,'which bears on the top of the socket, transmits the shockto the bodyand eectually prevents the post from being driven into thesocket.

G represents a collar surrounding a reduced portion or neck of the postbetween two confining shoulders or flanges thereon. The collar turns`freely on the neck, butis held from vertical movement by the shoulders.The collar is provided with lugs or ears, between which is pivoted toswing vertically on a rivet or the like g the inner end of a link H, tothe outer end of which a ring or link Iis pivoted to turn about ahorizontal axis at right angles to the pivot of the-link'H. Thisarrangement of the parts permits a universal movement of the tether (notshown) which is connected to the outer ring I and prevents it frombecoming twisted or wound on the pin in the movement of the animal aboutthe latter.

The body of the pin above described may. be shaped in any known orsuitable manner. It is formed from a single sheet-metal blank of thetriangular or tapering form shown in Fig. 3. The blank is bent centrallyby stamping or otherwise to give the trough or V shape to the body, andthe upper portions of the sides are bent toward each other to partiallyform the socket for the head, as shown in Fig. 4. The head-post is thenplaced in the partially-formed socket, and the sides of the socket arepressed together around the post, so as to tightly embrace the same.

The groove and rib of the socket are formed at the proper points tointerlock, respectively, with the rib and groove of the stud.

The pin made as herein described is simple and can be produced at a lowcost. It is strong and cannot be injured in driving the vsame into hardsoil with a tool or heavy object.

I claim as my invention- 1. A pin comprising a sheet-metal body which isprovided with longitudinal Web portions extending at an angle to eachother,and

a socket at the upper end of the body, a post IOO secured in saidsocket, means for preventing a longitudinal movement of the post in saidsocket, and a swivel-collar on said pin, substantially as set forth.

2. A pin comprising a sheet-metal body which is bent to providelongitudinal Web portions extending at an angle to each other, and asocket at its upper end, and a post secured in said socket and having ashoulder which bears on the top of the socket, substantially as setforth.

3. A pin comprising a sheet-metal body of substantially trough shape,the upper portions of the sides of the body forming a cyof May, 1902.
